حلقات مسطحة NAS1149-C1290R | مواصفات عسكرية | فولاذ مقاوم للصدأ 18/8 (8 / عبوة)

Installed these on a trailer rebuild and they didn't budge under torque, even in wet weather. The stainless steel finish still looks brand new after a month.

These washers handled the load distribution perfectly when I mounted a heavy shelf bracket. The 18/8 stainless steel is a nice step up from the cheap zinc ones I've used before, no rust worries here.

These washers fit perfectly on the 1/4" bolts I was using for a small metal shelf project, and the 18/8 stainless looks clean and resists rust well. The load distribution is noticeably better than the cheap hardware store alternatives I've tried before.
